Abstract: According to one embodiment, a camera module includes an image sensor and a liquid crystal panel. The liquid crystal panel includes an aperture portion, a liquid crystal layer overlapping the aperture portion, an electrode overlapping the liquid crystal layer, and a driver configured to drive the liquid crystal layer by applying a voltage to the electrode. The driver is configured to drive the liquid crystal layer based on a first control value and drive the liquid crystal layer based on a second control value. A first image captured based on the first control value is used to calculate a distance to a subject having a first brightness. A second image captured based on the second control value is used to calculate a distance to a subject having a second brightness.

Abstract: A depth calculating unit calculates a depth for each of a plurality of unit regions (for example, pixels) forming a depth map. A dividing unit divides an image region corresponding to a captured image into a plurality of partial regions. A noise removing unit removes, using a first parameter, noise from estimated depths calculated for a plurality of unit regions included in a first partial region. The noise removing unit removes, using a second parameter, noise from estimated depths calculated for a plurality of unit regions included in a second partial region. This prevents a problem in that an estimated depth that should originally be displayed is excluded from the depth map.
